' BUBBLE-BLOWER.

Application filed May 8, 1916. Serial No. 96,054.

that nature having a reservoir for the bubble-forming solution which is an integral part of the complete structure and is arranged in a novel and improved manner with respect to the blowing tube. My invention further comprises an improved form of cup or seat for the bubble; improved means for establishing or cutting off, at will, communication between the blowing pipe and the said reservoir; and 'otherfeatures, all as hereinafter described and more'particularly pointed out in the appended claims. The objects of my invention'are to improve the construction of bubble blowers; to produce a device which is, neat and compact, and which may be used without dripping of the solution and without detriment to the clothing of the user or to surrounding objects; to so construct the device that the blowing of very large bubbles may be possible; and generally to produce a device which, while compact and neat in appearance is simple in construction, may be produced at small expense, and is not readily broken or otherwise injured.

I will now proceed to describe my invention with reference to the accompanying drawings, and will then point out the novel features in claims. In the drawings:

Figure 1 shows a front elevation of the device and Fig. 2 shows a central longitudinal section thereof on a plane at right angles to that of'Fig. 1.'

In the drawings 1 designates a tube, usually formed of metal, and having a readily detachable mouth piece 2. 3 designates a bent tube, also usually formed of metal, secured to the lower end of the tube 1 and terminating inan enlargement 4 pro- Sip ecification of Letters Patent.

vided with a flaring cup 5, forming the bubble seat. voir provided with a central tube 7 through which the tube 1"(which tube is the blowing tube) passes. The reservoir 6 has at one side a filling aperture normally closed by a cap 8 having within it a pressure-balancing orifice 9.

The tube 7 has near its lower end, an

6 designates a solution reser orifice l0, and the pipe 1 has a corresponding orifice 11. When these two orifices 10 and 11. are in registry the blowing pipe 1 is in communication with the reservoir 6, and solution within that reservoir may flow down through tube 3 into the enlargement 4 at the base ofthe cup- 5; flow being facilitated by the inductive action of air blown through tube 1; for the holeslO and 11 are preferablyso small as to be capillary V in character so that little or no flow will occur through them except as a result of such inductive action. The tube 1 is adapted to be rotated through a small angle with in the tubev 7, and is provided with a pin 12 working inva slot 13 of a portion of the tube 7 projecting. out beyond the reservoir 6. When the tube 1v has been turned with respect to the tube ,7 so that the pin 12 is at one side of the slot 13, orifices 10 and 11 are in registry. When the tube 1 is turned with respect tothe tube 7 so that the pin 12 is at the opposite end of the slot 13, the orifices 10 and Ham out of registry and communication between reservoir 6 and tube lisshutofl. V

r The pin 12 and slot 13 not only serve to control position of the reservoir with respect to the tube 1, and therefore to control flow from the reservoir, but also serve to hold the reservoir in position, longitudinally, with respect to the tube 1. As clearly shown in Fig. 1, there is, at the center. of the slot 13, a gap permitting the reservoir to..be moved longitudinally of the tube 1, out of engagement with the pin 12, and therefore permitting the reservoir to be removed from the tube 1 after the bent tube 3 has been unscrewed from tube 1.

when the reservoir (3 has been filled, placing of the orifices 10 and 11 in registry for a moment (the hole 9 being open) permits a portion of the solution within the reservoir to fiow into the pocket 4. The amount so flowing may be regulated by closing the hole 9 after it is thought that a sufiicient amount of the fluid has passed out. This hole 9 may be closed readily by the finger of the user, thus stopping the flow from the reservoir more conveniently than could be done by turning the tube 1 so as to move orifices 10 and ll out of registry. In fact, during the blowing of bubbles it will be most convenient for these openings 10 and. 1-1 to remain in registry, the user keeping his finger over the orifice 9, except when it is desired topermit a. small quantity of the solution to flow outot that reservoir, and then closing'the orifice 9-quickly when a sutficient amount haspassed out. Orifices 10 and 11 will in general be moved out of registry one with the other only when the user is through with the use of the device for the time being. It will be seent-hat the rotatable tube 1 in connection. with the tube 7, the two having registering orifices 10 and 11, together constitute a valve controlling the fiow of solution from the reservoir. The orifice 9 will, in general, be so small that little orno flow of solution will occur throughit; it will be, practically, a capillary orifice.

It will be-apparent that, a small quantity of solution having been passed to the pocket at, it the user blow through the tube 1 a bubble will emerge from this pocket, will seat upon the cup 5, and will gradually enlarge as the user continues to blow. Desirably, the bore of the mouth piece tube will be so small or the bore of the bent tube 3 will be so small, that considerable pressure will be required for material flow of air through the tube. In this way premature destruction of: the bubble by too great air pressure will be avoided, also the user by reason of the pressure required, will develop increased strength of lung. The pocket a: is preferably of capacity to hold solution to make several bubbles.

The reservoir 6 may be filled most readily by means of a pipette of the rubber bulb type; i. 6., a device of the general nature of the ordinary fountain pen filler. Of course, before filling the reservoir the cap 8 will be removed, after which the reservoir may be filled readily with the pipette, and the cap 8 replaced.
